Needing to switch additional (non-ooma) phone

[VOIP VOICE]

I have an ooma phone and phone system and also an additional (Panasonic) phone that ooma had coordinated with my ooma system a number of years ago. It appears that this Panasonic phone is starting to have clarity issues so I'm wanting to change it out for another Panasonic phone that is part of the same set. A number of years ago this was done but think I may have had to call in on a cell phone(?) Part of my issue is that I only have a prepaid cell phone (limited minutes) so don't want to be spending a huge amt. of time waiting, etc. while this is (hopefully) done. also concerned that there won't be any snafus in this regard and that I'll still have my phone service or I'll have a real issue. I would like to have a manager or some other higher up employee help due to all of this, plus many times some of these regular employees have a hard time understanding the situation, and vice versa. Any way to reach managers, etc. at ooma for such help, and/or for them to acquire this info and get back to me? (The regular workers can't call back, from what one told me.) Help! and TYIA

Users can usually just plug third-party phones into the Telo (or Linx) PHONE jack themselves. They don't need to call customer support for that.
